  • Method for encoding a picture, computer program product and encoder
    Patent number: 8224102
    Abstract: A Method for encoding a picture with a first region and a second region is described wherein the first region is encoded according to a first encoding scheme, the second region is encoded according to a second encoding scheme and the second encoding scheme is carried out taking a parameter representing the visual perception of the second region into account.

  • Method and system for video quality measurements
    Patent number: 7733372
    Abstract: A method of measuring a quality of a test video stream, the method comprising measuring a content richness fidelity feature of the test video stream based on occurrences of color values in image frames of the test video stream; measuring a block-fidelity feature of the test video stream based on distortion at block-boundaries in the image frames of the test video stream; measuring a distortion-invisibility feature of the test video stream based on distortion at pixels of the image frames of the test video stream; and determining a quality rating for the test video stream based on the content richness fidelity feature, the block-fidelity feature and the distortion-invisibility feature measured.

  • Method for generating a quality oriented significance map for assessing the quality of an image or video
    Patent number: 7590287
    Abstract: A method for generating a quality oriented significance camp for assessing the quality of an image or video, comprising the steps of extracting features of the image or video, determining a perceptual quality requirement of at least one extracted feature and integrating the extracted features and the perceptual quality requirement of the at least one extracted feature to form an array of significance level values, thereby generating the quality oriented significance map.

  • Image and Video Quality Measurement
    Publication number: 20070263897
    Abstract: An image quality measurement system (10) determines various features of an image that relate to the quality of the image in terms of its appearance. The features include the image's blockiness invisibility (B), the image's colour richness (R) and the image's sharpness (S). These are all obtained without the use of a reference image. The determined features are combined to provide an image quality measure (Q).
